Motor Performance Equipment - Regenerative Dynamometer

RDS Regenerative Dynamometer Test System

The term "regenerative" describes the ability of the drive under braking conditions to convert the mechanical energy of the motor and connected load into electrical energy which is returned (or regenerated) to the AC power source. Regenerative drives can reclaim a majority energy produced from the device under test which can reduce the overall cost of testing.

Historically, the regenerative energy was wasted into heat using resistors bank. The MEA RDS solution is to return the energy back into the main line power supply, eliminating heat and providing a real return on investment, a compact/modular solution.

Features:

• Controlled by closed-loop field oriented, using auto tune servo drives.
• Controlled and stabilized DC supply for the frequency inverter, allowing stabile control of the torque or speed and high accuracy of the measurement.
• Combined control system that includes PC, OPLC (PLC with integrated operation panel), regenerative units, and VFD's which connect together with fast and reliable industrial CanBus and TCP/IP communications networks.
• Usage of AC Induction Servomotors, with square frame design and low moment of inertia, allowing excellent fast and accurate dynamic response in all ranges of torque and speed.
